The test has been moved to shared/, since it's a valid test, but it is no longer related to inlining, as the inliner no longer attempts to inline functions with inouts at all. Also, one function here (outParameterIgnore) actually invoked undefined behavior and has been removed. According to the GLSL ES2 docs: "If a function does not write to an out parameter, the value of the actual parameter is undefined when the function returns." SkVM leaves the value unchanged, so SKSL_TEST_CPU would pass, but a GPU might clear it (and in fact, my GPU does).
